Impact of a Magnetic Resonance Imaging (MRI) Scanner Exclusively Dedicated to Emergency in the Clinical Management of Patients Presenting With Diplopia or Dizziness

IRM-DU is a prospective observational single center study conducted in an emergency department to evaluate the impact of a MRI scanner exclusively dedicated to emergency in the clinical management of patients presenting with dizziness or diplopia.

The study will compare 2 strategies : after and before availability of a MRI scanner dedicated to emergency.

The primary endpoint is the proportion of patients with a diagnosis of stroke confirmed by imaging (MRI or Computed tomography (CT)) in the group "before implementation of the emergency MRI scanner" and the group "after implementation of the emergency MRI scanner".

The hypothesis is that the availability of a MRI scanner dedicated to emergency will improve the diagnosis of stroke in patients presenting with dizziness or diplopia, and will reduce Emergency Department stay, hospital stay and hospitalisation costs.

Treatment and study plan

Primary outcomes

  1. Diagnosis is established on the positive signs of stroke highlighted on the CT scan or brain MRI according to the examination performed

    Time frame: 18 months

    Proportion of patients with a diagnosis of stroke confirmed by cerebral radiology (MRI or scan according to examination) in the pre- and post-MRI groups.

Secondary outcomes

  1. Evaluate the time of care

    Time frame: 18 months

    Evaluate the time of care: time of realization of the examination of radiology (scanner or brain MRI), delay of passage in emergencies

  2. Number of CT and brain MRI requested by the emergency physician in the before / after groups

    Time frame: 18 months

    Number of CT and brain MRI requested by the emergency physician in the before / after groups

  3. Evaluate the usual management of vertigo and diplopia

    Time frame: 18 months

    Evaluate the usual management of vertigo and diplopia: number of CT and brain MRI requested by the emergency physician in the "before / after" groups; number of cerebral CT and MRI performed by the radiologist in the "before / after" groups

  4. Evaluate the rate of new consultations in emergencies

    Time frame: 18 months

    Evaluate the rate of new consultations in emergencies for a neurological reason in the month following the initial care in emergencies, and the rate of new hospitalizations for the same reason

  5. Rate of new emergency department visits for neurological

    Time frame: the month following initial emergency care

    Rate of new emergency department visits for neurological reasons in the month following initial emergency care

  6. Evaluate the irradiation rate

    Time frame: 18 months

    Evaluate the irradiation rate related to the initial radiological examination performed during emergency care
